Dispensing device



March 1936- F. J. McMACKIN DISPENSING DEVICE Filed July 25, 1935Patented Mar. 31, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to dispensing devices and more particularly to adevice for dispensing the contents of the flexible tubes containingtooth paste, shaving cream or the like.

The main object of the invention is to provide a device for easily andefliciently removing the entire contents of a flexible container.

A still further object of the invention is to provide a key attachableto the end of the tube 4) and adapted to coil the tube upon itself forremoving the contents thereof.

A still further object of the invention is to provide means to easilyremove the coiled and empty tube from the coiling device.

Other objects of the invention will appear as the disclosure progresses.The drawing is intended to merely indicate a possible embodiment of theinvention. It is obvious that the actual needs of manufacture maymechanical changes. It is therefore not intended to limit the inventionto the embodiment illustrated but, rather to define such limits in theappended claims.

For a more general understanding of the invention attention is called tothe drawing in which Figure 1 is a view of the dispensing device shownattached to a flexible tube.

Figure 2 is a section on line 22 of Figure 1 showing a portion of theend of the tube coiled.

Figure 3 is a section on line 33 of Figure 1. Figure 4 is a section online 44 of Figure 1. Referring now to the drawing in detail, nu-

spaced bars 4 and accommodate the end 6 of the tube and a handle memberI for manually coiling up the tube.

The parallel bars 4 and 5 adiacent the handle member 1 are restricted asat 8 where they pass through one of the eyes 9 ,of the key retainer. Thekey retainer is semi-elliptical in shape and provided with a coil to inthe center and another eye H opposite the eye 8.

The operation of the device is as follows: The eye -II is slipped on theends of the bars 4 and 5 as shown in dotted lines in Figure 1 and theend of the tube inserted between them. The eye is then replaced andthebars 4 and I5 revolved manually through the medium her! in ananti-clockwise cient contents of the tube are'expelled. After of thehandle mem-. direction until sufli use the tube can be closed up withthe usual cap and the entire device with the tube attached hung up inthe cabinet by the eye I 0 to be used again when necessary. After theentire contents are expelled the device can easily be removed from 5 thetube by removing the eye II from the bars and slipping off the coiledtube. The coil III will impart a sufficient amount of resiliency to thekey retainer so that it can be used indefinitely without breaking. Alsothe said coil can be 10 used as a means of support whenthe device is notin use by suspending the entire device on a hook through the medium ofthe coil. When the device is suspended the key retainer is swung out ofcontact with the body of the tube as shown in dotted lines in Figure 1.

It will thus be seen that I have provided a simple, eflicient and usefuldevice for expelling the entire contents of a flexible tube and whichcan flt all size tubes now on the market. Due to the restricted neckconstruction of the bars the key retainer cannot be entirely separatedfrom the forked key member.

Having described my invention, I claim:

1. In a device of the class described, a key member comprising twoparallel spaced bars to grip the end of a flexible tube and a handlemember at one end of said bars all made from one piece of material, thesaidbars, adjacent said handle member being restricted, a resilient key0 retainer mounted on said key member, said key retainer comprising asemi-elliptical spring element provided with eyes at the ends, one ofsaid eyes being mounted on the said restricted portions of the bars andthe other on the free end 3 of said bars.

2. In a device of the class described, a key member comprising twoparallel spaced bars to grip theend of a flexible tube and a handlemember at one end of said bars all made from one piece of material, eachof said bars adjacent said handle member having an inwardly bentportion, the inner faces of said inwardly bent portion of each bar beingin contact with each other, a resilient key retainer mounted on said keymember, said key retainer comprising a semi-elliptical spring elementprovided with eyes at the ends, one of said eyes being of a largerdiameter than the other eye, the smaller of said eyes being mounted atthe inwardly bent portions 'of the said bars and the larger of said eyesbeing mounted at the free end thereof, and a loop in thecenter of saidkey retainer for providing resiliency to said key retainer.
